Customary international lawCustomary international law is an aspect of international law involving the principle of custom. Along with general principles of law and treaties, custom is considered by the International Court of Justice, jurists, the United Nations, and its member states to be among the primary sources of international law. Many governments accept in principle the existence of customary international law, although there are differing opinions as to what rules are contained in it.

JurisdictionJurisdiction (from Latin juris 'law' + dictio 'declaration') is the legal term for the legal authority granted to a legal entity to enact justice.

Jus gentiumThe ius gentium or jus gentium (Latin for "law of nations") is a concept of international law within the ancient Roman legal system and Western law traditions based on or influenced by it. The ius gentium is not a body of statute law nor a legal code, but rather customary law thought to be held in common by all gentes ("peoples" or "nations") in "reasoned compliance with standards of international conduct". Following the Christianization of the Roman Empire, canon law also contributed to the European ius gentium.
Erga omnesIn legal terminology, erga omnes rights or obligations are owed toward all.

Erga omnes is a Latin phrase which means "towards all" or "towards everyone". In international law, it has been used as a legal term describing obligations owed by states towards the community of states as a whole.

The criteria are split into two groups: jus ad bellum ("right to go to war") and jus in bello ("right conduct in war").
